I prefer throwing down a Network for the simple reason that you prepare an army to throw into it and it's pretty much instant. Why would anyone wanna transport a few critters when you can overwhelm them with infinite amounts of anything.

Imagine destroying their mineral line with some banelings or zerglings .... nice.

I find uses for both. A lot of times, if you doom drop, you usually have to have enough to wipe them out, or you lose your forces. I like using overlords for banelings drops, but with nydus worms, you can spawn them, throw your entire army at their mineral line, and when they moblize, get out, or head back and defend. It can be harder to get nydus going though.

Nydus worms spit your units out one by one so I don't know how it could possibly be superior. Not to mention the worm is sitting building in their base for like 10 seconds and makes a lot of noise.

Doom drops can be dropped directly into the mineral line and will completely decimate enemy economy before they can even react.

OL drops are far superior. But like you said, A nydus coupled with an OL drop would #%#@.

If people don't notice the Nydus because you got one quickly and put it in their base outside their view, then spitting out units 1 by 1 is no bother, as you can afford the time. If your opponent has defenses setup such that he can kill the units coming out 1 by 1 so quickly that it wont amount to anything, than the Nydus is as useless as if they just killed it.

Hence why I said, if people are quick on their feet and notice the Nydus you try to put in their base, at that point you need to OL drop first before attempting a Nydus worm.

But in every other situation, whether for protecting an expansion, or for ganking someones base from behind, especially if they are slow to react, etc., then the Nydus worm is superior.

Even more so because OL drops can be negated by having a bunch of turrets around the side of their base, Nydus worm protection involves having defenses ready to protect your entire base, and early game that makes a person vulnerable to being hit on any front really, as some of their forces have to take time to get there as backup.

OL drops are viable at certain times- when your opponent has weak spots/minimal AA. But the baneling OL drop decimates, and it's a great way to confuse and anger your enemy while his eco is totally destroyed. Of course, nydus drops are superior in all other situations you listed.

Alot of strategies could come in play. Fake a nydus in his base and OL drop EXP. or vice versa, fake OL drop and nydus on Main while his attention is on your empty OLs. I love this game, it's chess on steroids.
